4. INSTALLATION OF THE BOILER
Read Chapter 3 - Boiler Location and decide upon the position of the boiler.
Installation of the boiler is straightforward but consideration must be given to access to allow flue
and air pipes to be pushed through walls and ceilings. The order in which the components are
installed will depend upon particular site conditions, but in general it will be easiest and most
accurate to install the boiler and then build up the flue outlet and air inlet pipes to the terminal - this
is the sequence described.
4.1
WALL MOUNTING
BRACKET
a
Place the bracket on the wall
horizontally
with
the
pre-drilled
holes
at
the
bottom
and
position
as
dictated by the template
supplied within the boiler
packaging.
b
Drill through the centre hole
of the bracket, plug the hole
and fix in position.
c
Using a spirit level make
sure
the
bracket
is
completely level and mark
the position of the other
screw holes.
d
Remove the bracket and drill
the holes in the positions
marked. Plug these holes.
e
Screw the bracket to the wall
using
screws
of
an
appropriate size for the wall
type (No. 12 x 2 inch wood
screws normally suffice).
4.2
MOUNTING THE BOILER
(after system cleaning and testing)
a
Lift and locate the boiler onto the stud and the two locating pegs protruding from
the wall bracket. (lift the boiler via the back frame only)
b
Lower the boiler for hanging on the two pegs.
c
Fix the boiler on the bracket stud using the nut and the washers supplied.
d
Make the gas, flow, return, condensate and PRV connections to the system.
Check all joints for tightness
DO NOT FIRE THE BOILER UNTIL THE CONDENSATE TRAP IS SECURED IN
POSITION.
4.3
ASSEMBLY PRACTICE
Remove all plastic debris and burrs when installing air intake piping. Plastic filings caused
by cutting muPVC pipe must not be allowed to be drawn into the combustion air blower.
Prevent dust entering the air intake when cutting on building sites. Blower failure which is
determined to be caused by plastic filings or other debris will not be covered by guarantee.
4.4
INSTALLING FLUE AND AIR PIPES
IMPORTANT - When installing the boiler on an existing system a new flue and air
intake system MUST also be installed. You must NOT re-use existing flue or air
pipework components.
NB:
When installing the boiler, consider:
Flue Spigot Assembly
The flue spigot (50mm muPVC) is inside the accessory bag.
